Bulletin Board
The bulletin board is a place on the switch where you can post information and
receive messages from other switch users, including Lucent Technologies per-
sonnel. Anyone with appropriate permissions can use the bulletin board for
everyday messages. In addition, Lucent Technologies personnel can leave
high-priority messages, which are displayed on the first 10 lines of the bulletin
board.
Busy Verification of Terminals and Trunks
Allows attendants and users of multi-appearance telephones to make test calls to
trunks, telephones, and hunt groups to check the status of an apparently busy
resource. With this feature, an attendant or multifunction telephone user can dis-
tinguish between a telephone that is truly busy and one that only appears busy
because of some problem. You can also use the feature to quickly identify faulty
trunks.
Call Charge Information
DEFINITY ECS provides two ways to know the approximate charge for calls
made on outgoing trunks:
■ Advice of Charge — For ISDN trunks
Advice of Charge (AOC) collects charge information from the public
network for each outgoing call. Charge advice is a number representing
the cost of a call; it is recorded as either a charging or currency unit.
■ Periodic Pulse Metering — For non-ISDN trunks
Periodic Pulse Metering (PPM) accumulates pulses transmitted from the
public network at periodic intervals during an outgoing trunk call. At the
end of the call, the number of pulses collected is the basis for determining
charges.
Call-charge information helps you to account for the cost of outgoing calls
without waiting for the next bill from your network provider. This is especially
important in countries where telephone bills are not itemized. You can also use
this information to let employees know the cost of their phone calls, and so
encourage them to help manage the company’s telecommunications expenses.
NOTE:
This feature is not offered by the public network in some countries,
including the United States.
